In one aspect, the invention relates to one or more rotatable elements and one or more stationary element such that the elements are arranged along a common axis of rotation co-linear with or substantially parallel to an optical path. The optical path is a portion of a sample arm of an interferometer. Further, the rotatable and stationary elements are configured to couple electrical signals and optical signals between a data collection probe and an interface unit or other component of an imaging system. In one embodiment, the data collection probe is a combination ultrasound and OCT probe. In one aspect, the invention relates to a rotary joint in which the optical fiber and a fiber optic rotary joint lie in the center of one or more conductive elements of an electrical rotary joint which are annularly disposed around one or both of the optical fiber and optical rotary joint.

Interface devices, systems and methods for multimodal probes

In part, the invention relates to a probe suitable for use with image data collection system. The probe, in one embodiment, includes an optical transceiver, such as a beam director, and an acoustic transceiver such as an ultrasound transducer. The optical transceiver is in optical communication with an optical fiber in optical communication with a beam director configured to transmit light and receive scattered light from a sample such as a wall of a blood vessel. The acoustic transceiver includes an ultrasound device or subsystem such as a piezoelectric element configured to generate acoustic waves and receive reflected acoustic waves from the sample.

Multimodal imaging systems probes and methods

Multimodal imaging systems, probes and methods

A method for bringing an IVUS and an OCT image into register. In one embodiment, the method includes obtaining an IVUS image of an area of a lumen; obtaining an OCT image of the same area of the lumen; determining the same asymmetry in each of the IVUS and OCT images; and overlaying the IVUS and OCT images and rotating them with respect to one another until the asymmetry in each of the IVUS and OCT images are in register, and determining the angle of rotation that resulted in the registration. In another aspect, the invention relates to a probe for OCT and IVUS imaging. In one embodiment, the probe includes a sheath having a first end and a second end defining a lumen; a marker that is opaque to light and ultrasound located between the first end and second end; and an IVUS/OCT probe head positioned within the sheath.
